Behind the Candelabra

"Cheyenne Jackson and his husband Monte Lapka have mutually decided to divorce. The couple have been together for 13 years and were married in N.Y. State two years ago. It is an amicable parting and, understandably, a private matter," a rep for the actor tells PEOPLE.

Jackson, 38, who has had roles on Behind the Candelabra, Curb Your Enthusiasm, 30 Rock and Gleewed Lapka in the Hamptons in 2011.

"I wanted him to be at once repellant and engaging, if that's possible. He reminded me of a certain genus and species of guy that you would see at Laker games during the Magic Johnson era," Lowe told EW.com.

Michael Douglas – simply great – plays Liberace, once upon a time billed as Mr. Showmanship. Wikipedians probably know him as a closeted Vegas piano act who performed under staggering amounts of fur, jewels and sequins – with his thick toupee, he looked like Bob Mackie's idea of a snow owl – and who died of complications from AIDS in 1987.
